Misleading error message if sqlite3 is not installed as exception is swallowed

This is similar to #1673, which has been fixed. But there is still a case when this can happen:
14 try: 15 try: 16 from sqlite3 import dbapi2 as Database 17 except ImportError: 18 from pysqlite2 import dbapi2 as Database 19 except ImportError, e: 20 import sys 21 from django.core.exceptions import ImproperlyConfigured 22 if sys.version_info < (2, 5, 0): 23 module = 'pysqlite2' 24 else: 25 module = 'sqlite3' 26 raise ImproperlyConfigured, "Error loading %s module: %s" % (module, e)
If the first import fails, and then the second import fails, you'll get this error message: "ImproperlyConfigured: Error loading sqlite3 module: No module named pysqlite2" when the error may really be that there was no module named sqlite3 available. (That was my particular problem.) The 'module' variable gets set based on the sys.version, but the exception is based on whichever one last failed. There's no pysqlite2 in Python 2.5, so if the first import fails under 2.5, you're going to get the misleading error message.
